e1000e_confi...fter_link_up(9)

💅 e1000e_config_fc_after_link_up(9) — like, the Kernel API Manual era 🎀

okay so bestie, buckle up, because we're diving into the Kernel API Manual and this one function is genuinely doing the most. it's e1000e_config_fc_after_link_up, and yes the name is a whole mouthful, i know, i know — the header got truncated to e1000e_confi...fter_link_up(9) and honestly? relatable. she's long. she's iconic. periodt. ✨

🌸 NAME 🌸

e1000e_config_fc_after_link_up — configures flow control after link. that's it, that's the vibe. lowkey does exactly what it says on the tin 🫶

---

✨ SYNOPSIS ✨

s32 e1000e_config_fc_after_link_up (struct e1000_hw *hw );

like, she takes one thing and gives you back an s32. no cap. 💅

---

🦋 ARGUMENTS 🦋

• hw — pointer to the HW structure. that's your hardware bestie right there, the whole struct, the main character 👑

---

💖 DESCRIPTION 💖

so here's the tea, bestie 🍓: this function checks the status of auto-negotiation after link up to make sure the speed and duplex weren't forced. like, we're doing a little vibe check on the link, making sure nobody snuck in and hardcoded anything. 🙈

if the link needed to be forced, then flow control needs to be forced also — they go together, fr fr, it's giving matching outfits. 🔥

and if auto-negotiation is enabled and did not fail? then we configure flow control based on our link partner. yes, our link partner. we're collaborating. we're being collaborative. we're literally building community over here 🌈✨

ngl bestie, that's the whole page — no warnings, no bug notes, no exit statuses hiding in here. she's short and she's sweet and she's very good at pcie. 😭
